| 目的：探讨蛇床子素对人肺癌细胞A549的杀伤作用及其机制。方法：将人肺癌细胞A549用各种不同的浓度的蛇床子素治疗后,采用MTT法检测蛇床子素对A549细胞增殖的抑制作用；通过流式细胞术检测A549细胞内DNA的含量测定蛇床子素对A549细胞细胞周期的影响；通过流式细胞术检测A549细胞用蛇床子素处理后细胞的凋亡； Western blot检测A549细胞蛇床子素处理后周期相关蛋白p-Cdc2和Cyclin B1及凋亡相关蛋白Bcl-2和Bax的表达。结果：蛇床子素可显著抑制A549细胞的增殖并诱导其发生凋亡。蛇床子素处理后A549细胞p-Cdc2、Cyclin B1、Bcl-2表达显著下降,Bax表达显著增高。结论：蛇床子素诱导人肺腺癌细胞进入G2/M阻滞并引起凋亡性死亡。 |

| objective: To explore the effects of Osthole on the proliferation and mechanism of A549 cells treated with Osthole. Methods: A549 cells were treated with various concentrations of Osthole. Cell proliferation was measured using the MTT assay. Cell cycle was evaluated using DNA flow cytometry analysis. Induction of apoptosis was determined by flow cytometry. The expressions of cell cycle related proteins Cyclin B1, p-Cdc2 and apoptosis relatedSproteins Bcl-2, Bax were evaluated by Western blotting. Results: osthole significantly inhibited the proliferation of A549 cells inducing apoptotic cell death and G2/M arrest. Western blotting demonstrated that Osthole down-regulated the expressions of Cyclin B1, p-Cdc2 and Bcl-2 and up-regulated the expressions of Bax in A549 cells. Conclusion: osthole induced apoptotic cell death and G2/M arrest of A549 cells. |
